How much Memory is needed to properly run MT4 Terminal

How much Memory is sufficient to run a MT4 Terminal? I have 1 Gig on my desk PC and it is just not cutting it. With the terminal up the available memory goes below 100k and have seen it down to 6,000 - I have used SBFX and now IBFX on a Demo and the results seem to be identical. Do these MT4 terminals really have to hog down 750,000 of my Gig memory?


Not sure if Memory is the origionator of the problem though? I am sure some of you have encountered same situations and or problems with the mt4 updates etc., etc.,.


I am ready to add memory, but just not convinced that this is the only problem. Could someone please give me some pointers into the right direction as to what I might need to do to stop this hogging of Resources? I would very much appreciate it!

Good question sometimes my 2gig Core2 Duo hangs and I have to close some charts and remove some indicators....

Hello there,

I don't think it is your computer "memory" or even MT4 problem but you put on a badly written indicator or EA. I have 3 MT4 terminal and 2 MT3 terminal open 24/7 on an old Pentium 3 833 with only 128M ram while it is still use for other internet things without any problems.

You need to find out what indicator/EA that's really give you the trouble - they may have some infinite loop in the code that can cause such problem. Then just don't use them~~(or you can change the code urself)

Hope that helps

Change your Chart settings to show less candles and close charts which you don't need.

My running MT4 platforms are using between 15mb and 290mb of memory. I'd say the average for me is about 45mb per terminal. I do have a backtesting platform with a lot of history and the charts set to show a large number of bars that uses about 1 gig with the charts loaded up as well. It's for weekend use at the moment. Puppy and winters have addressed most of the reasons for large memory usage.

What he said. A pc with 1 gig of memory is more than capable of displaying multiple MT charts, even with a fair amount of other "stuff" going on in the background. A couple of my machines are running with 512Mb ram and have no issues. I'd suspect that it's poorly written custom code that's at fault.

I really do thank all of you ..... for your input in trying to help me determine what my PC problem might have been!

I had downloaded a different Demo and after I installed it and opened the program, "the instant update window" opened up, and I just x'ed out of it a few times, thinking I didn't need to install it, and it now looks like this was the main reason of the Memory drain. and has now stabilized.

I also removed indicators and went through them to see if one of them might be dragging down the system. I will go through them again checking them for errors as well yet. I will also check the EA's I have uploaded in the system. OK great I should be PC alright now for one terminal! lol

One thing that has helped me a lot to unclog loose ends on my PC is CCleaner, what a time saver that has been! When you uninstall etc., it really helps remove the trash left over! IMO

You Guys are great! Puppy, winters, nvwine, Tesla, much appreciated! Thanks all!

UPDATE:
Well I spoke too quick, I still have problems with it. I will follow your instructions and try to see what indicators etc., might be causing the drain still. Thanks!

ok the .... #Signal_Bars_v6.ex4 .... was the culprit! ..... This indicator did not work with my metatrader Terminal, and was the indicator that was zapping my memory. You guys were right; just one badly written indicator can bring your PC to a complete standstill! Now I know this to be a fact. Thanks all of you for the input ....

[#Signal_Bars_v3.ex4 ..... seems to work fine which I now use instead]

I've had the same types of memory problems in the past few years and have always nailed it down to one of 3 things:

indicator loop
(indicator was poorly written and is falling through into an infinate loop)
- solution: pull all indicators and load one at a time while watching memory usage ... then either don't use the problem indicator(s) or edit them to correct problem

indicator pulling too many bars
(many indicators will show on EVERY bar showen thus if you have 100k bars in your history and are showing all of them, then the indicator will run each calculation on each of thes 100k bars at every tick received)
- solution: lower your bar count shown or edit the indicator to only show 2000 bars (or less)

too many indicators or windows
(intensive indicators do many calculations)
- solution: load fewer windows or find how to work without indicator (I have a couple of these that I really like to use and have edited them to clean up the code a bit. This helps, but I run them on one window and switch pairs. It does take a few seconds to load the new pair (on a 2 gig AMD, 3 gig ram, SATA drives), but it's less of a load than having all the windows setup)

There are other possibilities, but I've found that these three cover all MT4 memory issues I have personally run into.

Bear
Good pips to all ... bye

I stumbled on this thread when trying to find out how to remove an EA from the chart.

For comparison, I use MT4 in Linux under WINE emulation and each terminal uses around 50Mb of RAM. Running multiple terminals no problem with 512Mb RAM and a 1.7Ghz Centrino CPU on Ubuntu Feisty.

If your PC has a RAM drain, look at not only the badly written indicators but also your PC OS itself. Viruses and Trojans can eat your resources too. That's one of the reasons I use Linux instead of windows btw.

Hi Max, thank you for posting this as i have had the same problem which now works perfect. Thanks to Puppy, Bear, Tesla and Nvwine( sorry if i forget someone) for the solution I really appreciate your help.
